Abstract
The use in clinic of orthopedic dentistry with the latest materials and technologies, high-tech and possibilities can't radically change the quality of orthopedic treatment, so we continue to see a huge number of errors and complications that affect the reduction of the period of use of fixed constructions of dentures. The purpose of this study was the comparative analysis of quality of fixed dentures stages of their clinical use. The criteria for assessing the quality of dentures in the early and remote periods following selected indicators: discoloration, cracks, raccomandiamo, damage to the structure, in violation of its shape due to the abrasion. The quality of artificial crowns and bridges is determined by the duration of clinical use and their construction. So, in the early period of clinical use plastic crowns are higher quality than composite (respectively (96,8±0,8)% (92,1±1,6)%, p<0,05), which depends on the total frequency of certain manifestations of reducing the quality of construction (plastic – (3,2±0,8)%; for combined – (12,0±2,5)%, p<0,01) and share of prosthetic constructions with signs of declining quality (plastic – (1,4±0,1)%; for combined – (1,3±0,1)%, p<0,01). In the long term clinical operating plastic crowns are characterized by a more expressive reduction in the level of quality orthopaedic design than the combo (respectively (52,9±3,5)% and (39,1±3,7)%, p<0,05), which primarily is due to the general increase in the frequency of certain manifestations of the lower quality designs. In the early period clinical use plastic bridges are higher quality than composite (respectively (93,9±1,9)% (87,1±2,1)%, p<0,01), which depends on the total frequency of certain manifestations of reducing the quality of construction (plastic – (7,2±1,9)%, combined – (14,7±3,3)%, p<0,05) and, in contrast to crowns, quality of bridges not depend on homogeneity of structural material. In the distant period of clinical operation and plastic and composite bridges are characterized by a decrease of the level of quality orthopaedic design (respectively (55,2±2,2)% and (47,0±1,9)%, p<0,05). The decline in the quality of bridges is due to the general increase in the frequency of certain manifestations of reducing the quality of construction (plastic – (69,1±4,6)%; for combined – (65,2±5,0)%, p<0,05); however, quality of comparable structures were not significantly different and the average is 1,4±0,07. Thus, it is proven that quality of artificial crowns and bridges is determined by the duration of their clinical use. While in the long term clinical operating plastic crowns are characterized by high values of the quality indicator. The quality of the bridges and in the early and remote periods does not depend on homogeneity of structural material.
